Conceptual Physics Alive: Newton's Third Law

Conceptual Physics Alive: Newton's Third Law includes a digital video and questions set with answers. Observe Paul Hewitt teach in a classroom with real students, using engaging demonstrations and artwork. In this video, Paul Hewitt teaches Newton's 3rd Law: The notion that a force is a push or a pull is developed. The concept that forces always occur in pairs as interactions between one thing and another is supported with numerous examples, including a tug-of-war. Newton's 3rd Law Includes: Hewitt begins with "I can't touch you without you touching me in return." Then Newton's 3rd law is defined. Force defined as an interaction. Demonstration of blocks pulled by an elastic band. Demonstration of a tug of war with visitor, Helen Yan (co-author of the Next-Time Questions that accompanies the high school edition of Hewitt's Conceptual Physics). Fingers stretching a rubber band produce a single interaction. Likewise with the gravitational interaction between the earth and moon. Action,
